ROLLING SCREEN.

Specification of Letters Patent.

Application filed August 25, 1909. Serial No.--514,494.

To all whom "it may concern:

Be it known that I, CONRAD BAUER, a citizen of the United States ofAmerica, residing a't Knoxville, in the county of Allegheny and State ofPennsylvania, have invented a new and useful Improvement in RollingScreens, of which the following is a full, clear, and exact description,reference being had to the accompanying drawings, forming part of thisspecification.

This invention relates to screens, especially to rolling screens of theslat type, for windows, doors, awnings, and the like. Its primary objectis to provide a screen of this character, in which the slats may beturned or adjusted for the admission of light and air, and it consists,generally stated,"in the combination and arrangement of parts to behereinafter more fully set forth.

I will now describe my invention so that others skilled in the art towhich it appertains may understand and construct the same, referring tothe accompanying drawings, in which:

Figure 1 is a fragmentary front elevation showing my invention asembodied. in a screen for a window or similar opening; Fig. 2 is anenlarged fragmentary rear elevation showing the slat tilting mechanism;Fig. 3 is a similar view showing the tilting mechanism as mounted withina casing; Fig. 4 is a view taken on the line 4-40f Fig. 3; Fig. 5 is asimilar view taken on the line 5-5 of Fig. 3; Fig. 6 is a similarviewbut showing the slats tilted or swung to open position as distinguishedfrom Fig. 5; Fig. 7 is a horizontal sectional view taken on the line 77of Fig. 5; and Fig. 8

" is a view corresponding with Fig. 3 but showing the manner of shiftingthe slats for locking thereof against turning or swinging.

In describing my invention, the reference numerals 2 indicate a seriesof slats mounted together in parallel relation by means of the suitableflexible connecting device 3 which may be carried by a suitable. take-upor winding roll, as indicated by the numeral 3 in Fig. 2, at the top ofthe window frame or other frame-work 4. This flexible connecting devicecomprises the links 5 to which the. slats are pivotally connected as at6. In the drawings only one side of the screen is shown and thereforeonly one point of the screen is provided with the flexible connector. Aflexible connector may be mounted along each side of the screentherefore, extra long slats; the slats by reason of such central orintermediate pivotal support would be prevented from sagging.

In rolling screens of the slat type, the ends of the slats are guided inthe process of rolling by means of channel members or other suitableguides arranged at each side of the window-frame or other frame-work. Ihave indicated,.-in my present-device such a guideway or channel by thereference numeral 7. Itcomprises the members 8] which are pivoted at 9to the upright bar 10 carried by the framework 4:, and are provided withthe extending arm 11 which has pivotal connection with rod or bar 12 bymeans of which, through vertical movement of said rod or bar 12, themembers 8 may be shifted in unison for shifting or tilting the slats aswill be described below. Heads 13 are carried by ends of the slate andare adapted to be received by the members 8. These heads 13 are fixedlycarried by the slats so that when the members 8 are swung or tilted theslats will in turn be likewise tilted. Withthe shifting bar 12 in theposition shown in Figs. 3, 5, and 7, that is, against the upright bar10, which acts as a stop to limit the movement of the bar 12, themembers 8 are directly in alinement with one another, thereby forming apassageway for the heads 13 when the shutter or screen is caused to beraised or lowered in the process of rolling. The manner of shifting themembers 8 by means of the rod or bar 12 is clearly illustrated in Fig.'6 wherein the slats are shown as being shifted by the downward movementof the bar 12, to sub stantially a horizontal position from the verticalposition thereof shown in Fig. 5.

In'Fig. 8 the head 13 of one slat is shown as engaging the member 8 ofthe next ad jacent slat while still in engagement with its respectivemember .8. By shifting the slats to this position an 'eflectual lock isprovided for the slats 2, that is, the slats cannot be swung or tilteduntil each head 13 is caused to be brought back into engagement with J.member 8. It will be apparent that with this construction the screen orshutter may be partially lowered and the slats of the suspended portionof the screen tilted or swung to open position, provided the heads 13have been brought into direct engagement with the members 8.

The operation of my device will be read ily understood from theforegoing description of my invention.

It will be apparent that many changes may. be made in the constructionshown without departing from my invention and I do not therefore limitmyself thereto.

The advantages of my invention will be readily appreciated by thoseskilled in the art.

The device is simple, inexpensive, and durable, and by reason of itscompactness may be applied to an ordinary window frame or otherframe-work.

Having thus described my invention, what I claim and desire to secure byLetters Patent is- 1. In a screen, the combination of slats, flexiblemeans for connecting the slats together, a head carried by an end ofeach slat, pivotally mounted members adapted to receive the heads, andmeans for shifting the members, whereby the slats are caused to betilted.

2. In a screen, the combination of slats, means for connecting the slatstogether, heads carried by the ends of the slats, members pivotallymount-ed and adapted to receive the heads of the slats, arms carried bythe pivoted members, and means engaging with the arms, for rocking thepivoted memhere.

3. In a rolling screen, the combination of slats, means for connectingthe slats together, means for raising and lowering tlie screen, headscarried by the ends of the slats, a series of pivotally mounted membersadapted to receive and constituting a guide for the ends of the slats,and means for rocking the members.

In testimony whereof, I have hereunto set my hand.
